Question

How much voltage must be applied across a 0.20 Ω wire in order to create a 30 A current? (Please show work for it too)

Answer 1

V=6V

Step-by-step explanation:

Use the equation I=V/R and solve for V then use V=IR plug in the numbers.

V=IR

V=30(0.2)

V=6V

Answer 2

6 V

Step-by-step explanation:

By ohm's law :

V = IR

V = 0.2 × 30 = 6 V
